The Hachioji R&D Center at Casio Computer Co., Ltd., has developed an educational program for elementary school students in Japan. In August 2007, it began to offer learning opportunities that include site tours and school visit programs. In addition to three schools in Hokkaido, the program has so far provided learning opportunities to students at 17 schools in Tokyo.
The Hachioji R&D Center, the home of the program, is one of the most advanced environmentally friendly buildings in the Casio Group. Visitors can see the actual facilities the company is using and understand methods used to reduce environmental impact.
The students not only learn about Casio, but also the fun of product creation, including the history of the calculator. They even get a chance to take apart and reassemble calculators.

Hamura City, located in Tokyo, is promoting tulip cultivation as an effort to preserve fallow rice fields and to make effective use of rice fields after their crops have been harvested. Casio has been a foster-sponsor of these tulips since 2004. Every year, many tourists visit these tulip fields, the largest in the Kanto region. Since 2006, Casio has also been a foster-sponsor involved in the preservation and cultivation of Ohga lotus plants, an ancient form of lotus flower excavated from ruins dating back to ancient times (c. 400 BC~300 AD).

Exhibiting at Eco-Products 2011

Every year Casio exhibits at Eco-Products, the largest environmental trade show in Japan. Held at Tokyo Big Sight from December 15 to 17, 2011, Eco-Products 2011 marked its 13th year with more than 180,000 visitors in attendance and over 700 companies and organizations setting up exhibits to display their environmentally friendly products and services.


Casio has exhibited each year since Eco-Products began. In 2011, Casio showcased its initiatives to help build a low-carbon society and protect biodiversity under the theme of “Harmony with Nature.” The concept behind this year’s show was the creation of a sustainable society through projects that emphasize the natural environment and the precious blessings it provides: energy and natural resources. Based on this concept, Casio showcased Casio Green Star products and a wide range of environmental initiatives undertaken by the Casio Group.


Casio’s stage featured an interactive quiz for visitors and a witty performance by a stand-up comedian describing everyday examples of saving energy and caring for the natural environment. The exhibition space provided accessible explanations of the environmentally friendly aspects of Casio’s products through catchy slogans and a quiz in the form of a “stamp rally,” by which visitors collect stamps to win prizes. In addition, Casio’s popular calculator assembly classes, held every year at the event, attracted a large number of children, teens, and students.


By continuing to exhibit at Eco-Products in the future, Casio will keep informing people about its wide range of environmental efforts and work to promote new concepts and policies for approaching the environment.

Initiative to Save Otoguro Cherry Trees

Otoguro cherry trees (scientific name: Cerasus serrulata, or "Komatsunagi") are a type of wild cherry that comes into full bloom in mid April. They have white blossoms measuring 5 to 6 cm, and the leaves emerge at the same time as the blooms.
In the late 19th century and early 20th century, this cherry tree variety was growing along the banks of the Fuefuki River, which flows through present-day Chuo City in Yamanashi Prefecture. The Otoguro cherry gets its name from the Otoguro Embankment in the Otoguro District, where the trees used to bloom. This variety of cherry tree has long been a favorite of the people in that region.

However, with the improvement of the Fuefuki River in 1932, the Otoguro cherry trees were cut down. Mr. Matsuhiko Tanaka of Otoguro District grew grafted seedlings from a few remaining descendent trees, in order to bring back the historic Otoguro cherry. His activities eventually came to fruition, and a volunteer group for saving the Otoguro cherry was established in 2002. The Tamaho-cho (now Chuo City) Board of Education lifelong learning center led the whole community in efforts to save and cultivate Otoguro cherry trees. This was achieved through cutting and grafting methods using a few remaining descendents of the original trees.

As part of Kofu Casio's environmental activities, the company offered to participate in the cultivating of this endangered type of cherry tree, for the purpose of preserving the variety and beautifying the landscape around the plant. Kofu Casio received a donation of trees from Tamaho-cho (now Chuo City) in 2004, and over the three subsequent years, the company planted more than 30 Otoguro cherry trees. All the transplanted trees took root, and every spring they provide a beautiful display of blossoms for people to enjoy on the grounds of the Kofu plant.

The Otoguro cherry serves as a symbol of the connection between Casio and the people of Chuo City. The company is proud of its early participation in helping to preserve the tree variety, as part of its biodiversity protection efforts on the local level. This is just one example of Casio's vision of harmony among people, businesses, and living things.
In fiscal 2013, the Kofu Office of Casio Business Service Co., Ltd., took over Kofu Casio’s effort.
